This study demonstrated that maintaining endotracheal tube cuff pressure at 30 cm H2O through monitoring every 8 h did not result in a greater incidence of under-inflation (pressures < 20 cm H2O) compared to a 4-h monitoring schedule. This study did not find a statistically significant difference in VAP incidence between the two monitoring frequencies. So, it is suggested to use the 8 h interval without compromising patient safety or increasing the risk of micro aspiration and subsequent ventilator-associated pneumonia (VAP). These findings warrant further investigation through larger, multi-center studies to confirm their generalizability and robustness across diverse patient populations and healthcare settings. This less frequent monitoring schedule also offers the potential benefit of reducing nursing workload, allowing for more efficient allocation of nursing resources.
